摘要:
An ultrasound imaging system includes features to reduce speckle and time gain compression noise. A handheld ultrasound system may include beam forming electronics and digital waveform generators to generate the transmitted pulses with fine grained apodization to improve coherence and reduce speckle. Speckle filtering may be included in the ultrasound system. Features to reduce quantization noise and improve the time gain compression response may be provided.
